In this February 2026 short, Matthew Berman highlights Google’s Gemini 3.1 Pro benchmark table and explains the pattern-matching structure of ARC-AGI-2. Google reports 44.4% on Humanity’s Last Exam without tools, 77.1% on ARC-AGI-2, 94.3% on GPQA Diamond and 80.6% on SWE-Bench Verified under the listed settings. The 94.3% figure is for GPQA, not ARC-AGI-2.

ポイント
- Google reported 44.4% on the full Humanity’s Last Exam without tools for Gemini 3.1 Pro Thinking (High).
- Its ARC Prize-verified ARC-AGI-2 score was 77.1%; the nearby 94.3% is the GPQA Diamond score.
- Google reported 80.6% on SWE-Bench Verified using a single attempt, close to the listed Opus 4.6 result of 80.8%.
- These historical benchmark results depend on the model and evaluation settings and do not establish performance on every task.

Gemini 3.1 Pro benchmark highlights
Berman points to the no-tools Humanity’s Last Exam score and explains ARC-AGI-2. He then highlights the GPQA and coding results shown in Google’s benchmark table.

Google’s launch table shows Gemini 3.1 Pro Thinking (High) at 44.4% on the full Humanity’s Last Exam without tools. I also highlight ARC-AGI-2, which gives examples of a visual transformation and asks the system to solve a new instance. Google reports an ARC Prize-verified score of 77.1% on that benchmark.

The 94.3% figure shown next is for GPQA Diamond, a scientific-knowledge benchmark, rather than ARC-AGI-2. Google’s table also reports 80.6% on SWE-Bench Verified with a single attempt, close to the 80.8% listed for Claude Opus 4.6. These are launch-era results under specific configurations, not a guarantee of equivalent performance across all coding tasks.
